Thermoelectric cooler for DMK41AU02.AS camera consisting of a Peltier chip from an old electric cooler, and pentium 4 CPU cooler. The camera was overheating and shutting down while solar observing when the ambient temperature was above 90 degrees F. The pentium 4 CPU cooler basically consists of a copper heat sink and a 12VDC fan that blows through the heat sink. The cold side of the peltier chip is against the camera housing. The hot side of the peltier chip is against the heat sink of the CPU cooler. Thermal compound helps conduct the heat or cold between the chip and the camera or heat sink.
